Freeze casting of composite PIM-1 and activated carbon hydrogen adsorbent monoliths, from chloroform, toward high-strength pressure vessel inserts.
Porous Cu bodies with complex shapes were fabricated by freeze-casting and vacuum sintering water-based CuO slurry. The sintered bodies showed no noticeable macroscopic defects and good shape tolerance. The interconnected pore tunnels were observed by electronic microscopy. The pore size became smaller and the porosity and volume shrinkage of sintered porous bodies decreased with the increase o...
Background Since the treatments of long tracheal lesions are associated with some limitations, tissue engineered trachea is considered as an alternative option. This study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. Methods Nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°C/min) ...
Freeze casting with bioceramics affords the opportunity to create next generation of bone graft substitutes. Because its versatile material fabrication process and effective methods structural control, freeze helps meet many criteria that are required viable substitute biomaterials. In combination biocompatible resorbable ceramics ceramic composites can offer growth through osteoconduction, thi...
Objective(s): Bone tissue engineering is aimed at the fabrication of bone graft to ameliorate bone defects without using autografts or allografts. Materials and Methods: In the present study, the coprecipitation method was used to prepare hydroxyapatite (HA) nanoparticles containing nandrolone. To do so, 12.5, 25, and 50 mg of nandrolone were loaded into poly(lactic acid) (PLA)/nano-HA, a...
